I try to replace all of my circular needles with the Addi whenever I can afford them. There is nothing to compare with the ease of knitting with them. I make blankets for babies and weddings and try to only use these needles for speed and ease, especially with lace patterns. I also make hats all fall and winter and those I prefer in the round--no seams. I have made a few socks and quite a few purses and would not use any other needle.
